A researcher has estimated a linear model to study the effect of weekly household income x; (in $100) on weekly household expenditure on food y; (in $). Using a sample of size v = 40, she found that Vi= 83.42 + 10.21x;, R2 = 0.384 (43.41) (2.09) and Zi=1(V)-V)2 = 500,000 and the sample mean of X; is 19.605. Then, ' [1=1(1- V)2 =58,000 Ob. N Zi=(),-V)2 = 96,000 OC. EN= (),-V)2 = 192,000 [1=1(07- V)2 = 384,000 Oe. None of the above is correct
